This politician has a strong record of voting according to conscience. He or she (no preference, but I'll use "she" as Green politics is more "feminine" than "masculine" in its values) is, however, concerned that she doesn't lose touch with her electorate, and has been known to sound out constituents on a divisive issue before casting her vote at Westminster. She might abstain if her own political views and those of her constituents are strongly at odds. rnrnOf course she has a strong affinity with Green Party policy, but with her science background, she is quite a rationalist. For instance, her support for alternative health provision doesn't quite go as far as homoeopathy (she wants to see peer-reviewed evidence its efficacy before she agrees to it being available in the NHS), and she's comfortable with the idea of GM techniques - as long as they're kept in the lab or used for therapeutic purposes. This is what makes her an asset to the Green Party: she doesn't come across as an radical, rather as a principled politician who can clearly articulate how Green politics necessarily entails economic and social justice, as without environmental protection, neither of these is really possible.
